A cloud SDK endpoint override that sends service calls to a local process such as LocalCloud instead of a public cloud endpoint.
Unset overrides before real-cloud validation.
What Localhost cloud API means here
A cloud SDK endpoint override that sends service calls to a local process such as LocalCloud instead of a public cloud endpoint.
- Environment variables are the usual routing mechanism.
- Unset overrides before real-cloud validation.
How to use the term safely
In LocalCloud content, this term should not imply production replacement, legal permission, hidden credentials, or complete cloud parity. It describes a bounded local-development workflow that still needs license review and release validation against real Google Cloud.
Use the sandbox deliberately
- Permitted workflows use local endpoint values and should stop rather than fall back to real Google Cloud or real credentials. The Public Preview License permits individuals and organizations, including for-profit companies, to use LocalCloud for non-production internal development, testing, CI, evaluation, and pilots.
- LocalCloud emulates bounded local development workflows. Validate application behavior against real Google Cloud before production deployment.
- Before production deployment, unset LocalCloud emulator environment variables and validate behavior against real Google Cloud.
Keep the agent on the supported path
- Agent routes — Agent sandbox entry points.
- Compatibility — Service support boundaries.
- Compatibility matrix — Check current support boundaries before relying on a local-only test.
- Service catalog — Review every LocalCloud service, endpoint, and limitation.
- SDK examples — Use standard Google Cloud SDKs pointed at localhost.
- Seed data — Load deterministic fixtures for repeatable agent and CI runs.
